A lightweight option in the media center OS race, GeeXboX gives a full media PC solution in your pocket by virtue of its Linux
LiveCD foundation. Boot it up anywhere and access media on your hard drive, discs or on the Internet without reconfiguring your entire system. The 1.2 release throws in 64 bit support for x86 processors, HDTV and widescreen optimizations, plus a Win32 installer to load it to the HDD if you so desire. Pictured above is a peek at the upcoming 2.x interface, but in the meantime head over and give version 1.2 a try right now.
